Epstein–Barr Virus Antibodies IgG / IgM
The Epstein–Barr Virus (EBV) Antibodies IgG / IgM blood test measures antibodies produced by the immune system in response to infection with EBV. Epstein–Barr virus is a very common virus and is best known as the cause of infectious mononucleosis (often called glandular fever). Most people are exposed to EBV at some point in their lives, often during childhood or early adulthood.
Antibody testing helps distinguish between a recent infection and past exposure. Understanding this difference can be particularly helpful when investigating prolonged fatigue, fever, swollen glands, or other unexplained symptoms.

What is EBV and how does the immune response work?
Epstein–Barr virus belongs to the herpesvirus family. After initial infection, the virus remains dormant in the body for life. The immune system produces different types of antibodies at different stages of infection.
IgM antibodies usually appear early in infection and suggest a recent or active immune response. IgG antibodies develop later and typically remain detectable for life, indicating past exposure and immune memory.
Why might I need EBV IgG / IgM testing?
This test may be recommended if you have symptoms such as persistent fatigue, sore throat, fever, swollen lymph nodes, headaches, or unexplained illness lasting several weeks. It is commonly used when glandular fever is suspected.
EBV antibody testing can also help clarify the cause of abnormal liver function tests or prolonged recovery after a viral illness. In some cases, it is requested as part of a broader investigation into immune or infectious causes of ongoing symptoms.
What do the results mean?
The pattern of IgG and IgM antibodies helps indicate whether infection is recent, past, or unlikely. For example, the presence of IgM antibodies usually suggests recent infection, while IgG alone indicates previous exposure.
Results must be interpreted together with symptoms and, in some cases, additional EBV markers. Your healthcare professional will explain what your result means for you and whether further testing is needed.

The test is performed using a simple blood sample collected during a short appointment. The procedure is routine, and our clinical team will ensure you are comfortable throughout.
